I was testing the role for the first time and wanted to run it in --check mode to verify the behaviour, but it would fail. Here is the error TASK [linux-system-roles.storage : get required packages] ***************************************************************************** An exception occurred during task execution. To see the full traceback, use -vvv. The error was: NameError: name 'devices' is not defin ed fatal: [localhost]: FAILED! => {"changed": false, "module_stderr": "Traceback (most recent call last):\n File \"/home/bblasco/.ansible /tmp/ansible-tmp-1651110898.850052-489119-163256305427217/AnsiballZ_blivet.py\", line 102, in <module>\n _ansiballz_main()\n File \ "/home/bblasco/.ansible/tmp/ansible-tmp-1651110898.850052-489119-163256305427217/AnsiballZ_blivet.py\", line 94, in _ansiballz_main\n invoke_module(zipped_mod, temp_path, ANSIBALLZ_PARAMS)\n File \"/home/bblasco/.ansible/tmp/ansible-tmp-1651110898.850052-489119-1632 56305427217/AnsiballZ_blivet.py\", line 40, in invoke_module\n runpy.run_module(mod_name='ansible.modules.blivet', init_globals=None , run_name='__main__', alter_sys=True)\n File \"/usr/lib64/python3.8/runpy.py\", line 207, in run_module\n return _run_module_code( code, init_globals, run_name, mod_spec)\n File \"/usr/lib64/python3.8/runpy.py\", line 97, in _run_module_code\n _run_code(code, mo d_globals, init_globals,\n File \"/usr/lib64/python3.8/runpy.py\", line 87, in _run_code\n exec(code, run_globals)\n File \"/tmp/a nsible_blivet_payload_1xe7hh39/ansible_blivet_payload.zip/ansible/modules/blivet.py\", line 577, in <module>\n File \"/tmp/ansible_bli vet_payload_1xe7hh39/ansible_blivet_payload.zip/ansible/modules/blivet.py\", line 578, in BlivetDiskVolume\nNameError: name 'devices' i s not defined\n", "module_stdout": "", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error", "rc": 1} I googled the problem and came across this Red Hat KB article: https://access.redhat.com/solutions/6726561 I am already using Python 3, and was using localhost with connection = local. I tried to run the playbook in regular (not --check) mode, and it ran perfectly. Subsequent executions of the playbook in --check mode generate no errors either. I have reproduced the issue on two separate machines. Steps to generate the error Create a playbook that uses this role Run in check mode - Result = error as per above Run same playbook in regular mode - Result = success Run in check mode again - Result = success Environment info OS: Fedora 32 (also reproducible on Fedora 35) Ansible version: ansible-2.9.21-1.fc32.noarch AND ansible-2.9.27-1.fc35.noarch Link to the playbook I am testing with: https://github.com/benblasco/fedoralaptop/blob/master/nuc_storage_samsung.yml
